Answer:
Step-by-step explanation:
Givens
Area = L * w
w = x
l = x + 4
Area = 32
Solution
32 = x(x + 4)
32 = x^2 + 4x
x^2 + 4x - 32
(x + 8)(x - 4)
Only x - 4 is going to make any sense
x - 4 = 0
x = 4
The width is 4
The length is 4 + 4 = 8
4*8 = 32 which is the area.
Answer:
16
Step-by-step explanation:
The differnce of 28 and 12 is 16 because, 28-12=16 and 16+12=28
his average test score would be 82
you add together all the test scores
90 + 76 + 84 + 66 + 96 + 89 + 73 =574
and then you divide that number by how many scores there were
574 ÷ 7 = 82
